get_graph_info {gasper}

Retrieve Information Tables about a Specific Graph from the SuiteSparse Matrix Collection

Description

get_graph_info fetches the overview tables about a specified graph/matrix from the SuiteSparse Matrix Collection.

Usage

get_graph_info(matrixname, groupname)

Arguments

matrixname

Name of the matrix/graph for which to fetch information.

groupname

Name of the group that provides the matrix/graph.

Details

The tables contain detailed information and properties about the graph/matrix, such as its size, number of non-zero elements, etc. Visit https://sparse.tamu.edu/ of see SuiteSparseData to explore groups and matrix names.

Value

A list of tables with detailed information about the specified matrix/graph:

• "Matrix Information"

• "Matrix Properties"

• "SVD Statistics" (if available)

Note

The rvest package is used for parsing HTML, if it is not installed, the function will prompt for installation.
